3 Claims.

This invention relates to the production of wool bats for quilts and objectively is directed to the provision of a new and improved quilt bat of especial lightness, a bat having advanced heatinsulating qualities, and particularly one in which matting of the Wool fibers is obviated and in which the produced quilt may be repetitively washed with substantially negligible shrinkage.

The invention consists in a new method of carding the wool in which the fibers thereof are separated by intervening threads of silk, and in the employment of this carded silk and wool in a multiplicity of layers of which the alternating fibers of wool and threads of silk characterizing each stratum are disposed to lie at substantial right angles to the fibers and threads of contiguous stratums.

Describing the process in more particularity,

I machine-comb the wool and silk longitudinally in the course of which the fibers and threads are fed into the machine to have the former separated one irom another by the threads of silk. This operation, considering the formation of the wool fibers which are characterized by barb-like lateral projections commonly referred to as swords, and further considering the wiry nature of the silk and consequent resistance to contraction, functions to restrain the Wool fibers in that the swords are caused to penetrate the epidermoid coat of the silk. The bat produced from the materials so carded is essentially stratiform and has its layers of interlocked wool and silk sharply defined by laying the same, one upon another, with the directional course of the materials of each layer at substantial right angles to the directional course of its subjacent and overlying stratums. A bat should desirably be constituted of twelve or more layers.

The quilt, using this bat, is completed by the application of suitable coverings of woven material, desirably taffeta or other dressed cloth for the upper side and muslin or other non-dressed and soft-weave cloth for the under side of the quilt. It will be apparent that the non-dressed cloth permits ready transmission of body heat to the bat wherein conduction is opposed by the produced air cells which occur between the several layers, this inherent non-conductive characteristic being complemented by the dressed-surfac top covering.

What I claim, is:

1. The method of producing a quilt which consists in forming a stratiform bat with the several layers each composed of silk and wool of which the threads of silk extend parallel with and in intervening relation to the filbers of wool and with the directional course of the alternating fibers and threads of one layer disposed at right angles to the fibers and threads of next adjacent layers, covering the upper side of the bat with a woven cloth of a dressed-surface character, and applying to the bottom of the bat a woven covering of a non-dressed character.

2. The method of producing a quilt which consists in applying to the opposite sides of a silk and wool bat woven coverings of which one is of a dressed-surface character and the other a non-dressed character.

3. The method of producing a quilt which consists in applying to the opposite sides of a quilt bat woven coverings of which one is of a dressedsurface character and the other a non-dressed character,
